Our verdict

A large-room HEPA purifier with strong published CADR numbers, a laser sensor for PM1/PM2.5/PM10, and a 3-year warranty, best suited to spaces up to roughly 1,800 sq ft.

Overview

The successor to Coway's widely reviewed AP-1512HH, rated to purify 900 sq ft in 30 minutes or 1,800 sq ft in 60, with a washable pre-filter and a combined HEPA plus activated carbon Max2 filter.

This is a named successor product, positioned against its own predecessor rather than as a generic newcomer, and it leans on that lineage in its marketing. The HEPA filtration is tested to the IEST-RP-CC007 standard by SGS at speed level 1, and Coway notes performance in your own space may vary from the lab figures. The iF Design Award mention is an industrial design award, not a performance certification, worth keeping separate from the CADR and VOC numbers.

  • CADR: Dust 242, Smoke 240, Pollen 249
  • 900 sq ft in 30 minutes, 1,800 sq ft in 60 minutes
  • Megascan laser sensor with PM1/PM2.5/PM10 readout
  • 3-year limited warranty, sub-19 dB sleep mode

Who it's for

Suits a buyer furnishing a large living room or open-plan space who wants documented CADR figures (Dust 242, Smoke 240, Pollen 249) and a laser particle sensor rather than a basic on/off unit. Less necessary for a single small bedroom, where a smaller, quieter unit covers the space with a smaller footprint.

Pros and cons

Pros
  • 1,800 sq ft rated coverage with documented CADR numbers
  • Laser sensor tracks PM1, PM2.5 and PM10 separately
  • Digital filter life display removes the guesswork on replacement timing
  • 3-year manufacturer warranty, longer than most in this category
Cons
  • Combined HEPA/carbon Max2 filter likely costs more to replace than a basic HEPA-only swap
  • Performance figures are lab-tested and Coway itself notes real-room results vary
  • Larger and heavier than compact single-room purifiers

Performance notes

The Max2 filter combines HEPA and activated carbon in one stage rather than as separate cartridges, reducing more than 99.5% of tested VOCs and fumes like NH3 and CH3CHO alongside 99.97% of particles down to 0.3 microns. Smart Mode reads the laser sensor continuously and adjusts fan speed on its own, dropping into Eco-Mode when air is already clean and into a sub-19 dB Sleep Mode when the room goes dark, while drawing a stated maximum of 56W, about 20% less than the prior model.

A digital display counts down from 100% to 0% separately for the washable pre-filter and the Max2 HEPA/carbon filter.

How loud is it on the lowest setting?

Coway rates Sleep Mode as low as 19 dB, with a stated maximum power draw of 56W across all settings.
